LAMP-BURNER.

SPECIFICATION forming partbf Letters Patent N0. 240,763, dated April 26, 1881. Application tiled February 18, 1881. (No model.)

To all whom it may concern:

Be it known that I, CHARLES REISTLE, of Brooklyn, in the county of Kings and State of New York, have invented an Improvement in Lamp-Burners, of whichthe following` is a specification.

This burner is adapted to the kind of lamp known as the student-lampi but instead of -the burner being a fixture, as has heretofore been usual, the same is removable, and the wick is raised and lowered bya ratchet or toothed wheel.

In the drawings, Figure l is a vertical section of the lam p-burner complete. Fig. 2 is a plan at the line ww. Fig. 3 is a section ofthe removable chimneyholder and cone separate from the rest of the burner, and Fig. 4 is a plan of the drip-cup separately.

The oil is supplied by the pipe c from the reservoir to the space between the burner-tube b and air-tube c, as usual, and d is the dripcup. i

At the upper end of the burner-tube b there is a screw-collar, e, that receives the base f of the removable burner. Above this base fthere is a tube, y, similar to the tube b, rising as high as the top of the air-tubec, and around the same is the ring h, forming a support for the wick raiser or ratchet lo, that has a button- `head, as usual, and it acts through a slot in the tube g.

Within the tube g there is a wick-raising tube, l, having holes for the points of the ratchet-wheel l7c to act in when raising or lowerin g the wick n. The wick n is to be attached to this tube l by means of small spurs turned inwardly from the metal of the tube, or by being sewed into holes near the bottom, or by the lower end ofthe tube. being slotted for the wick to be sewed to the bars between the slots; or, if the wick is flat and rolled into a cylindrical form there may be an inner ring connected to the tube l, so that' the wick can be tied around the same. By this construction the burner and wick can be unscrewed and taken off the burner-tube for inserting or removing the wick', and the wick will be raised bodily and uniformly by the action of the tube land ratchet, and the lamp can be cleaned with facility when necessary. The oil must 5o not rise above the level of the screw-collar, but should stand aboutone inch below the same.

The chimney-holder m and the cone o are removable from the burner-tube. I have improved the same by making this removable por- 5 5 tion fm. in two pieces, so that they are cheaper and stronger than heretofore.

The gallery-ring s, that is perforated and provided with a central opening, is in one piece with the chimney-holding spring m, the same 6o being drawn up by dies and cut to the proper shape, and the cone o is adapted to set around the tube g, and it is slotted or perforated for the passage of air to the flame, and its base is a horizontal flange, the edge of which is receivedrinto the recess formed at the junction of the gallery-rin g and chimney-holder, so that the two parts are connected at this point. The cone and chimney-holder` are easily removable from the burner-tube, and the gallery-ring 7o forms a guide to steadythc parts at the bottom t The drip-cup is made so that theaccumulation of oil in the same will not close the air- Openings, as sometimes is the case when the oil is forced over by carelessness. This I accom plish by extending the top of the drip-cup conically and cutting holes in the same that extend to a higher level than the edge of the drip-cup, so that the holes will remain open 8o when the oil overflows from the cup. This will prevent the oil catching fire, as sometimes happens when the ordinary drip-cup is full and the air-holes become closed.

The capillary attraction sometimes causes the Oil to draw over and run down the outside of the burner-tube, and it may spread upon and drip from the outside of the'drip-cup. I prevent this by the downward projections 10 inside the drip-cup, either in the form of lips 9o turned down below the holes or as a downward flange. The oil draws down and drips into the cup from the lower edges of these downward projections, instead of spreading upon the outside of the drip-cup. 9 5

I claim as my invention- 1. In an Argand burner, the combination, with the air-tube c, burner-tube b, and dripcup d, of the screw-collar e, removable tube g, and Wick-raising Wheel k, substantially as set forth.

2. The combination, with the removable burner-tube g and wick-raising Wheel 7c, of the wick-raising tube l, having a rowof holes for the Wick-raiser, and the Wick secured to the said tube, substantially as set forth.

3. The removable gallery-ring and chimneysprin gs formed rof one piece of metal7 said gallery-ring being perforated and adapted to surround the burner-tube, in combination with the perforated cone adapted to t the burnertube at the upper end and connected at its lower edge to the metal of the chimney-holder 15 and gallery, as set forth.

4:. The combination, with the drip-cup, of the downward projeotionsl() within such drip-cup, for the purposes and as set forth.

Signed by me this Sth (lay of February,'A. 2o D. 1881.
